do it i was severely disappointed in the m when i test drove it i had a m and i i picked up a z vette for k and never looked back i put about k of upgrades into it for track days i dd it its amazing worth every cent the ls is bulletproof i heard there may be some issues with the ls in the c z but well have to wait and see on that if you have any problems its going to stem from the transmission and diff more than anything along the driveline luckily parts are dirt cheap i will probably be upgrading my tranny and diff in the near future rpm has raceready stuff for cheap
